Be it known that l, FRANCIS D. Sin-inn, a i

citizen of the United States, residing at Bath, in the county of Northampton, State of Pennsylvania, have invented certain new and useful Improvements in Rabbeting-Planes; and I do hereby declare the following to be a full, clear, and exact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to planes, and more particularly to those for cutting rabbets, and has for its object to provide a device of this nature which may be adjusted to cut rabbets of different widths and different depths and in which means will be provided for preventing the tearing of the wood at the edge of the rabbet.

Other objects and advantages will be apparent from the following description, and it will be understood that modifications of the specific construction shown maybe made and any suitable materials may be used without departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevation of the plane. Fig. 2 is a top plan view. Fig. 3 is a front view. Fig. T is alongitudinal section taken on line 1 T of Fig. 2. Fig. 5 is a section of one of the slotted plates and the pertions carried thereby, taken longitudinally of the plate.

eferring now to the drawings, the present invention comprises a base-plate 5, having a handle (5 secured to its upper face adjacent to its rearward end and having an upwardlyextending wall T at one edge which is formed integral therewith. Formed transversely of the base-plate, in the under face thereof, are dovetail grooves 8 and 9, which are disposed adjacent to the rearward and forward ends of the baseplate, respectively, these grooves opening through the side edges of the base-plate as shown, and disposed in each of the grooves 8 and 9 are dovetail members 10, which are arranged for sliding movement within the groove. The dovetail members 10 lie tlush'with the under face of the baseplate 5,

and secured to these members is a bead 11, which extends longitudinally of the base'plate and lies against the under face thereof, and this head is movable transversely of the baseplate with the members 10 and is arranged to lie at times flush with the outer face of the wall 7. The members 10 extend outwardly beyond the edge 12 of the base-plate which lies opposite to the edge from which the wall 7 extends and have secured thereto the downwardlyturned ends 13 of slotted plates 14:, which lie upon the upper face of the baseplate 5 and which are disposed with their slots 15 in registration with threaded openings 16 in the base-plate. with which are engaged thumb-screws 17, the shanks of which lie in the slots 15, and these thumb-screws are operable to clamp the plates 1i against movement, thus preventing movement of the bead 11, as will be readily understood.

The base-plate 5 has a transverse slot 18 formed thercthrough which extends from side to side thereof and which connnunicates with an opening 19 in the wall 7, so that the forward end portion of the base-plate is supported only by the portion 20 of the wall 7 and by the head 11, the slot 18 lying between the grooves S and 9, as shown. its cutting edge 21 in the slot 18 is a bit 22, having an extension 23, which lies in the opening 19, and this blade is mounted upon the base-plate and is arranged for longitudinal and lateral :uljustment in the old and wellknown way. At the side of the blade 22 opposite to the wall T is a guard-plate 23, which extends over the end of the slot 18, as shown.

Disposed against the outer face of the wall 7 and adjustable longitudinally thereover is a gage 2i, which comprises a slotted stock 25, which is disposed with its slot 26 engaged with the shank of a thumbscrew 27, which is engaged in a threaded perforation 28 in the face of the wall T, and by means of which the stock may be clamped at different points of its vertical movement, and secured to the lower end of the stock is the gage-plate 29, which extends longitudinally of the baseplate 5. Formed upon the inner face of the stock 25 is a rib 30, which is engaged in a groove 31 in the face of the wall 7. This ar- Disposed with rangement prevents other than vertical movement of the gage.

Formed in the outer face of the wall 7 and communicating with the under face of the base-plate is a recess 32, having lateral extensions 33, and disposed in this recess is a blade 34:, having wings 35, which are disposed in the extensions 33, and this blade is reversible to lie with its cutting edge 35 extending upwardly within the recess or projecting downwardly below the under face of the base-plate 5, the wings 35 being arranged for interchangeable engagement with the extensions 33 of the recess to permit of this reversal, and the blade may be held in either position by a screw 36, which is passed through a perforation therein and is engaged with a threaded socket in the wall 7, the head of the screw lying flush with the outer face of the blade.

Formed upon the upper face of the baseplate 5, at the forward end thereof, is a transversely-extending flange 37, which is joined at one end to the wall 7, this flange and the wall having a web 38, which acts with the flange 37 to form a brace for the forward end portion of the base-plate.

In use the bead lies moved away from the edge of the base-plate from which the wall 7 extends a distance equal to the width of the rabbet to be cut, and the gage 24: is moved upwardly from the under face of the baseplate to gage the depth of the rabbet, after which the blade 34: is disposed with its cutting edge 35 extending below the base-plate In operation the bead 11 lies against the edge of the board to be rabbeted, and the blade 22 coming into engagement with the surface of the board as the plane is moved forwardly thereover cuts the board away until the rabbet is of the correct depth, when further cut ting by the blade will be prevented by the gage 24 coming into contact with the upper face of the board. Duringthis operation the blade 3 cuts into the board, as will be readily understood, thus preventing tearing of the wood.

If desired, the stock 25 and the gage-plate 29, which comprise the gage 24, may be formed integral, as shown in the drawings.

What is claimed is- A rabbeting-plane comprising a base-plate having transverse dovetailed grooves in its under face, dovetailed members engaged in the grooves, a bead carried by the members and extending longitudinally of the baseplate, slotted plates connected with the dovetailed members and lying against the upper face of the base-plate, set-screws engaged in the base-plate and projecting through the slots of the last-named plates, said set-screws being arranged for operation to clamp said plates against the base-plate, and a cutting-bit for the plane.

In testimony whereof I afliX my signature in presence of two Witnesses.
